Automobile-bumper



WALTER S. ERAZEXEOF AURlEtA, ILLINOIS.

AUTOlVOBLE-BU To all whom t may concern: u l Be it knownthat I, WALTERS. Frazier, a citizen of the United States, and a resident of Aurora,inthe county of Kane and State of Illinois, have inventedcertain new anduseful improvements -in Automobile-Bump ers, of which the following is aspecification, reference being had to the 'accompanying` drawings Myinvention relates to bumpers or enders for automobiles, and it is theobject ol `my invention to provide a new and.V improved form of bumper,which shall be simple in construction and easy to .manufacture withoutthe necessity for extensive machine operations. thereon, which shallhave a nicely graduated resilient strength to rovide the desiredyielding to blows of lig iter intensity while at the 'same time havingthe required rigidity necessary for meeting the heavierblows, and whichshall be readily land easily applied to an automobile so as to bemaintained properly in position thereon. rEhe preferred means by which lhave accomplished my several objects are illustrated in the accompanyingdrawings and are hereinafter specifically described. That which lbelieve to be new and desire to secure by Letters Patent is set forth inthe claims. l, In the drawings,- `Figure l is a perspective view of thepreferred form of my improved bumper.

Fig. Q is a )erspective view of the device illustrated in Figi butshowing the device in position upon. the front end of an automobilewhich 1s shown informally and partially broken away.

Fig?) is a perspective modification.

Referring to Figs. `l and 2 for a showing oit' my improved form cidevice, 10 indicates the transversely-entending contact bar olf mydevice which in the construction shown isin the form of a strip ofresilient metal bowed out slightly between the ends of the device. Atthe ends oil the bumper, 'the strip is given a rounded turn inwardly to.provide integral inwardly-preiacting arms l1 and 1Q by vwhich thebumlper mounted Lupen an automobile, as is iereinaifter de scribed. Atthe inner end of each of the 'arms 1l and l2, the strip is again given arounded turn to project directly toward the bar, 10, providing thusposts 13 and il which stand normally a short distance from view showingv a Application filed January 2, 192.0. Serial No. 312:834?.

the bar l0 and substantially at right angles thereto. Y

My bumper is secured in position by means of bracketsl and 16 which areconnected to the arms ll and l2 respectively by means of clips i7 whichembrace theel-ms and the turned ends ci the brackets. The brackets ,l5and 16 are provided with able clips of any approved type for connect,ring` them rigidly with the i' ameworl oi the automobile, either inliront et the automobile or in rear thereof as may be desired. In theconstruction illustrated, the brackets' l5 and 16 are secured by meansof hooks 'i8 to the forward ends oi the chassis bars i9 of an automobile20. Y

The clips 17 have a sliding fit about the arms ll and l2 and the turnedends oiE the braeketsand areeasily adjustable along the arms so as topermit a ready accon'nnodation of the bumper to diiierent 'filaires-oi;automobile in which the chassis bars or other appropriate parts to whichthe bumper is to be attached are located at diil'erent distances apart.For holding the clips 17 in position upon the brackets l5 and i6 andholding the arms ll and l2 from moving laterally with respect to theclips, set-screws 17a et any appropriate type are mounted. in the clipsadapted to provide the necessary pressure for holding the clips in thedesired. adjusted position, and serving also to hold the arms frommovement with respect to the brackets. By this means, an euasyadiustment to as tine a degree may be desired is always available, an l,'this is effected without the necessity 'for puncturing the resilientn'ietal strip at any point. ln this way .l am enabled to provide abumper oi man1 mum strength with inspect to the weight oli the stripemployed.

ln use, when pressure is applied upon the linnnper at any point 'uu-onits outer face, the bumper is adapted a yield quite readily to anyconsiderable pressure, by reason oli the comparatively great length oiEthe resilient bar l0 wl'cb is supported only at its outer ends, andfurther by rea-son of the resiliency oi' the arms li and l2 and oit thecurved bar portions at the ends ci the bumper. ln many cases auchmoderate lrnr ness ci tlicbumperwill be tion for the automobile., byreason ol the yielding ci' the obstacle, or by reason ci the automobilebeing brought to stop. in other cases, the pressme is continued untilsuiiicient pretecl 'lill ing a transversely-extendinq resilient bar thebar l0 is brought into Contact with one or both et the posts 13 and lll,at which time the etieetive resilient strength of the bumper and theconsequent protection afforded thereby are greatly increased asis to bedesired.

Referring now to the modilied form of device shown in Figw, the bar l0,the arms ll and l2, the brackets l5 and 16, the clips l? are the same asthose 'already de scribed. ln this form ot' device, however, instead ofturning the ends of the arms ll and l2 for providing posts i3 and 14,1have provided posts 2l and 22 Fixed in any suitable manner upon theinner tace ot Vthe bar l0 and adapted to be brought into contact withthe straight end portions 'of the arms fi` and 'l2 upon the applicationof the requisite pressure to the bar lO, just as the bar l() oit' theconstruction of Fig. l is brought into Contact with the ends of theposts 13 and 14 of that construction.

By the use of my improvements, l have provided a construction which canbe adjusted easily to lit cars of different frame widths, which isadapted to be held firmly in position by its attaching means, and whichis so constructed and arranged that its parts are readily accessible.for cleani ing, plating, polishing, or enameling, l have also provided aconstruction by the use of which a moderate initial pressure is applied,but the arrangement of which is such that when a greater effectivestrength is necessary the parts are reinforced positively for affordingthe requisite strengtli.

TWhat I claim as my invention and desire to secure by Letters Patent,isi l. A bumper for an automobile compris'- a transverselyextendingresilient bar,

arms formed integrally therewith and tending inwardly along said bar,and posts interposed between said arms and said. bar substantially atright angles thereto adapted by their contact to support said bar fromsaid arms.

2. A bumper for an automobile compris- 7 arms formed integrallytherewith and extending inwardly alo said bar, and a post interposedbetween the at each end or the bumper'and said bar substantially atright angles thereto, being supported by one ing atransversely-extending resilient bar,

arms formed integrally therewith and einu tending inwardly along saidbar, and posts carried by said arms at their inner ends extending`toward said b ar substantially at right angles thereto but normally outof contact therewith` adapted by Ycontact with said bar to allo-rd apositive support thereto.

el. A bumper ifor an automobile comprising a transversely-extendingresilient bar, arms formed integrally therewith and extending inwardlyalong said bar, and posts formed integrally with said arms and eXtending directly toward said bar substantially at right angles theretobut normally out of Contact therewith adapted by Contact with said barto afford "a positive support thereto. Y

A. bumper for an automobile comprising a transversely-extenydingresilient bar, arms formed integrally therewith and extending inwardly'along's'aid bar, and a post interposed betweenthe arm at each end oi thebumper and said bar, being supported by one of said parts but normallyout of contact with the other part, said post being adapted. by pressureapplied to said bar to be brought into contact with the part with whichit is normally out of Contact, such contact being substantially at rightangles whereby a positive support is afforded to said bar.

6. A bumper for lan automobile compris# ing a transverselyextendingresilient bar, arms formed integrally therewith and ex-g tendinginwardly along said bar, brackets having turned ends for securing saidarms in lixed' position with respect to an autoincbile, clips embracingsaid arms and the turned ends of said brackets and slidable along saidarms, and set-screws carried by said clips adapted to hold the clipsfrom movement out of vadj usted position respect to said brackets andsaid arms and to hold the arms `from movement with respect to thebrackets.
